#3 cylinders
Page 1 of 1
#3 cylinders
Not to beat a dead horse, but I wanted to do a sanity check and see if I was losing it. Perhaps all #3's are not created equal. It wouldn't surprise me.
The reason I was curious is that besides #4/5 cylinders #1/3 are my second favorite. I usually snap them up when I see them.
Anyway I had a #3 on a black widow....

Re: #3 cylinders
ok.. that's a dual-bypass ported SPI piston/cylinder set there.. are they usually non-SPI.. or single-port... or both? This is something I'm just learning about.
Re: #3 cylinders
Yours looks like one of the #3s that may have
come on the Venom, Ron. The old thin wall doesn't
have the teeth of the thick walled one, I know. No sub-
induction, single bypass, no taper.
I'm going to try the old #3 on a nos BabeBee assy
I bought years ago. (I added the incorrect needle)
Hey, brand new Bee!
Report next weekend.

There are a lot of different cylinders. Best bet would be to visit the Wikipedia page. I don't think it's completely accurate, but it will give you an idea.

Re: #3 cylinders
The number 3 seems to have been used on many different cylinders so there really is no telling exactly what the cylinder porting is by just the number.
Re: #3 cylinders
From Martin Hepperle's site.
#3
Open ports(not slit)
1 Bypass
0 Boost
NO SPI (later: YES)
Used in Mercedes car
I wonder how many different #3s are out there.

Re: #3 cylinders
And this from Joe Klause(to add to the confusion).
No.3. A two bypass cylinder that initially did not have the bottom of the exhaust ports milled low enough to provide sub-piston induction. Later, the exhaust milling permitted sub-piston induction, and the outside was ground for use with an exhaust-restrictor type throttle, and the top fin was milled.

Re: #3 cylinders
That's too funny...
The picture I posted above is a #3 dual bypass, SPI and not ground for an exhaust throttle.
I think Jacob is right the #3 can be just about anything.

Re: #3 cylinders
3 (three; /ˈθriː/) is a number, numeral, and glyph. It is the natural number following 2 and preceding 4.
That's it!
Bob
edit: I just figured it out. The thinking at Cox may have been-It's not a #1 or #2, and definitly
not a #4 or #5........stamp a 3 on 'em.
Next week, the #8!
